Reaction of an optically active (1-methyl-2,2-diphenylcyclopropyl)trimethyltin (I) with bromine (or iodine) afforded 1-bromo-(or iodo)-1-methyl-2,2-diphenylcyclopropane (II) with a small degree of retention of configuration. This is best interpreted in terms of radical mechanism for the cleavage of the cyclopropyl carbontin bond in (I) by bromine or iodine.
光学活性的(1-甲基-2,2-二苯基环丙基)三甲基锡(I)与溴(或碘)反应,得到1-溴-(或碘)-1-甲基-2,2-二苯基环丙烷(II)。保留程度低的配置。用自由基机理可以最好地解释这一点,该机理是通过溴或碘裂解(I)中的环丙基碳锡键。
